To perform these tasks, the SQLIOSim utility simulates the user activity and the system activity of a SQL Server system. The SQLIOSim utility simulates the read patterns, the write patterns, and the problem identification techniques of SQL Server. To help maintain appropriate data integrity and security, we recommend that you perform stress tests of your I/O subsystem before you deploy SQL Server on new hardware. The SQLIOSim utility more accurately simulates the I/O patterns of Microsoft SQL Server.įor more information about SQL Server I/O patterns, see SQL Server I/O Basics, Chapter 2. The SQLIOSim utility has been upgraded from the SQLIOStress utility. However, if you have to perform benchmark tests and determine the I/O capacity of the storage system, you should use the Diskspd tool. These tests simulate read, write, checkpoint, backup, sort, and read-ahead activities for Microsoft SQL Server. You can use this tool to perform reliability and integrity tests on disk subsystems. This article describes the SQLIOSim tool. This article also contains download information for the SQLIOSim utility. The SQLIOStress utility was formerly known as the SQL70IOStress utility. The SQLIOSim utility replaces the SQLIOStress utility. It is recommended to use these updated versions of the tool to simulate the IO activity on the disk subsystem. When you install SQL Server, you find the SQLIOSim tool in the BINN folder of your SQL Server installation. Starting with SQL Server 2008, SQLIOSim is included with the SQL Server product installation. Original product version: SQL Server Original KB number: 231619 Summaryįor Microsoft SQL Server 2005, SQLIOSim was shipped as a separate download package. This article describes how to use the SQLIOSim utility to perform stress tests on disk subsystems to simulate SQL Server activity.
